In the recent past, a new approach emerged on how medicine should be practiced to keep us far healthier than we used to be.
Instead of acting only when something is broken in our body the preventive approach takes preemptive measures to optimize our body's performance, and either prevent the outbreak of diseases in the first place or catch them as early as possible, when treatment is still relatively easy.
On the most basic level of prevention, we don't even need specialized tests or equipment.
We start by evaluating how to protect the vital components of our body from disease and aging. Also, we implement a daily supplementation regimen that includes countermeasures to the known processes of aging wherever possible.
Backing up our Stem Cells
A lot of exciting research is going on in the field of regenerative stem cell treatments. New organs are already created in the lab from stem cells and therapies to rejuvenate individual parts of a body, like the complete cardiovascular system, are in development. If we want to take advantage of these technologies, once they are available, we need stem cells to start with. Those can be generated by changing normal skin or fat cell back into stem cells that can be multiplied and then used for treatment.
Unfortunately, when we are in need of stem cells a few decades from now, we would use skin or fat cells that are 30 years older and might have accumulated a lot of genetic errors and other damage. It would be best to have cells as young as possible, preferably already stem cells when we need them. For newborns, there is a general procedure of extracting stem cells from the umbilical cord and deep freezing them for future use.
Now adults can store their stem cells too. The body keeps stem cells for blood production in the bone marrow. Using a particular medication, part of these stem cells can be released into the bloodstream where they can be extracted in a dialysis-like procedure, and deep frozen for much later use (decades). The body replenishes the remaining bone marrow stem cells automatically.
Today various companies are offering adult stem cell extraction and storage.
